Which Linux distros support DVD-RAM format?

I don't have a personal experience for you, but I did have a look in the #!Crunchbang forums and a few of my fellow users have listed their machine specs that include DVD-RAM functionality. Plus #!Crunchbang is very lightweight distro.

Name: Gateway MT6729 Notebook Processor: Intel® Pentium® Core 2 Duo processor T2330 1.6 GHz, 1 MB L2 cache, 533 MHz FSB Screen: 15.4-inch WXGA (1280 × 800) RAM: 2048 MB 667 MHz DDR2 SDRAM (2 × 1024), Operates at 533 MHz HDD: 160 GB 5400 RPM SATA Optical Drive: 8x Multiformat Dual Layer DVDRW with DVD-RAM Graphics: Intel® Graphics Media Accelerator X3100, Up to 384 MB of Dynamic Video Memory Network: 10/100 Ethernet LAN, 802.11a/b/g Wireless, Bluetooth dongle (aftermarket) Other: 4 x USB2.0, 1 x Firewire, 5-in-1 Card Reader

Works perfectly with the #!

So I might suggest logging into the forums and asking there. #!Crunchbang Forums

Good luck.

Thanks for your suggestion. I'll try to follow up on it further a bit later.

For now, though, I just had a quick look for system requirements at the #!Crunchbag Forums, and the posts were not encouraging. I'm used to running with Puppy Linux or SLAX fully in RAM in well under 500MB, and my perception is that that would be impossible with #!Crunchbag. The fact that users are flailing about on this topic in the absence of essential documentation is also unappealing.

The indication of DVD-RAM capability on a system doesn't mean much per se, since most "super-multi" burners have supported DVD-RAM for the past three or four years at least.
